Mayo, taken with the third overall pick in the 2008 draft by the Minnesota Timberwolves, said in a statement that the positive test was the result of taking an over-the-counter supplement that contained the banned steroid DHEA (dehydroepiandrosterone).

"I'm extremely disappointed that I'm going to miss the next 10 games, particularly as our club is making a push for the playoffs," Mayo said in a statement.
